Contract specifications must state minimum hourly rate—Stipulation for payment—Residential and commercial construction work.

(1) The specifications for every contract for the construction, reconstruction, maintenance or repair of any public work to which the state or any county, municipality, or political subdivision created by its laws is a party, shall contain a provision stating the hourly minimum rate of wage, not less than the prevailing rate of wage, which may be paid to laborers, workers, or mechanics in each trade or occupation required for such public work employed in the performance of the contract either by the contractor, subcontractor or other person doing or contracting to do the whole or any part of the work contemplated by the contract, and the contract shall contain a stipulation that such laborers, workers, or mechanics shall be paid not less than such specified hourly minimum rate of wage. If the awarding agency determines that the work contracted for meets the definition of residential construction, the contract must include that information.

(2) If the hourly minimum rate of wage stated in the contract specifies residential construction rates and it is later determined that the work performed is commercial and subject to commercial construction rates, the state, county, municipality, or political subdivision that entered into the contract must pay the difference between the residential rate stated and the actual commercial rate to the contractor, subcontractor, or other person doing or contracting to do the whole or any part of the work under the contract.
